Climate change will cause food insecurity: study

Climate scientists and agricultural researchers have got together for the first time, producing a new study that identifies areas vulnerable to food insecurity from rising global temperatures -- otherwise called 'hot spots'. The study found that in some areas, the growing season will be cut by five per cent. That means current varieties of staples such as beans, maize and rice will no longer be viable.

The study follows another report released this week by charity Oxfam, which predicted food prices could double in the next 20 years -- in part because of a changing climate.
